 * Copyright (c) 2001-2020 Ravenbrook Limited.  See end of file for license.
 * Portions copyright (C) 2001 Global Graphics Software.
 *
 * Detect the target platform using predefined preprocessor symbols
 * defined by the build environment.  The symbols are derived from the
 * documentation, or, in the case of GCC, from the compiler itself.
 * References to the documentation appear above each detection line.
 *
 * For more details on how this file fits into the MPS build system,
 * and an explanation of all the MPS_* defines, see design.config.pf
 * "MPS Configuration" <../design/config.txt>
 *
 * .macos.ppc.align: MacOS / PowerPC requires 8 bytes alignment (in
 * general).  See "Mac OS Runtime Architecture", table 4-2.
 *
 * mpstd.h fails if it cannot detect the platform (even if CONFIG_PF_*
 * is specified).  This is intentional.  mpstd.h does *not* allow
 * CONFIG_PF_* to override the platform as detected from preprocessor
 * symbols.  This is intentional. [This needs justifying. RB 2013-05-11]
